Abstract

A method for providing an output signal (58) for storing of user data on a data carrier (37) is provided. The method comprises the steps of receiving (11) the user data, encoding (12) the user data according to a predetermined encoding scheme and converting (13) the encoded user data to the output signal (58). The encoding according to the predetermined encoding scheme results in irregular distances between detectable signal elements which have equal signal values and at least a predetermined run length. However for some control loops, said distances should not be too large. According to the invention the step of encoding comprises providing (14b, 15b) additional detectable signal elements in the encoded user data in disagreement with the encoding scheme. Thereby the method results in limiting the distance between the detectable signal elements.
